[mythtv-users] Network adds too much overhead for HD frontend

I'm trying to run a frontend on 2GHZ P4 laptop with a radeon 7500.
The frontend can just manage to display HD mpeg2 files that are local.
Mythfrontend uses about 70% of the CPU and Xorg a little over 20%, with
about 5% idle.
Over the network to the backend there is 0 idle on the same files, with
frequent prebuffering pauses. This is on a 100mbit wired network
connection. Top shows about 5% software interrupts (%si) which are close
to 0 when its operating off the local disk.
Is the added network overhead consistent with other's experience?
My first thought was wondering if I could increase the size of the
buffer used in prebuffering. However, if there really is just not enough
CPU thats probably just going to change the timing of the pauses.
